▎ 摘　　要

NOVELTY - Preparing reduced graphene oxide film involves freezing aqueous dispersion of graphene oxide and freeze-drying to obtain oxide graphene gas-gel. The reduced graphene film obtained is subjected to photoreduction to obtain reduced graphene oxide film. USE - Method for preparing reduced graphene oxide film (claimed). ADVANTAGE - The method enables to prepare reduced graphene oxide, that has improved utilization rate of solar energy and photo-thermal conversion efficiency.
